Embodiment 1
[0029] A paperless digital direct-injection printing process for all-polyester brushed cloth, comprising the following steps:
[0030] (1) Prepare sizing slurry: the sizing slurry includes the following components in weight percent: modified starch 2-5%, formic acid 1-3%, nanopowder 1-4%, sodium dihydrogen phosphate 0.2-0.8 %, the rest is water;
[0031] (2) padding and sizing: dipping and rolling the whole polyester brushed cloth twice in the prepared slurry, and the liquid rolling rate is 60%;
[0032] (3) One-time drying: For one-time drying, first heat up to 85°C for 2 minutes, then heat up to 125°C for 20 minutes, and finally heat up to 165°C for 1 minute;
[0033] (4) Digital inkjet printing: Make an inkjet printing model through computer digital drawing, and then use a digital color printing machine to directly spray the drawn pattern on the above-mentioned all-polyester brushed cloth with high-temperature dispersion ink. The ambient temperature during printing is 22-3...
